as the compound modifier, preserving the rest of the definition.
- Line 52: Update the proposal’s stakeholders frontmatter to replace TBD with
the actual named PPE, host-integration, policy, and security/privacy
stakeholders who own or approve the proposal.
- Around line 14-15: Update the experimental feature criterion to name the Cargo
feature and specify that it must be forwarded through every crate boundary
crossed by the existing policy-engine feature, so it remains disabled by default
and is active in server builds when enabled.
- Around line 646-649: Define the host-facing body-delivery API and sequencing
in the proposal: deliver transformed request content to model.evaluate and
complete request evaluation before dispatch, then deliver transformed response
content and complete response evaluation before release. Specify how Praxis
branch subchains receive this content despite not executing body hooks.
- Around line 715-717: Update the proposal’s deliverables to explicitly cover
the prompt-injection/tool-restriction and PII/response-withholding stories,
including their examples, regression coverage, Praxis configuration, integration
tests, and README updates. Keep the existing WAF-inspection and semantic-routing
deliverables intact.
- Around line 47-49: Align the graduation criterion with the validation section:
state that live checks are optional for individual backends but at least one
hosted and one local live check are mandatory overall, using consistent wording
in both sections.

Name the decision-model feature and its crate forwarding.
The criterion says the feature is flagged in policy and praxis, but it does not name the Cargo feature. It also does not state how that feature reaches the crates between the server and the filter. The existing policy-engine feature is forwarded through the server, filter, and protocol crates. An implementation that follows this criterion can omit a boundary. The flag would then stay inactive in a server build.

The validation section requires at least one hosted and one local live check, while the graduation criterion says live checks are optional. State that checks are optional for individual backends but mandatory overall, or use matching wording in both sections.

Define the host-facing body-delivery contract.
current_http_request promises bounded body content, but the proposal only names illustrative selectors and says that hosts must deliver content. Define the host API and sequencing that provide transformed request and response content to model.evaluate. The contract must ensure request evaluation completes before dispatch and response evaluation completes before release. It must also account for Praxis branch subchains, which do not execute body hooks.

Define artifacts for the missing primary stories.
This PR adds only the proposal, so it does not provide policy or Praxis artifacts for prompt-injection/tool restriction or PII/response withholding. The proposal gives detailed examples for WAF inspection and semantic routing, but its deliverables do not identify the corresponding examples, regression coverage, Praxis configuration, integration tests, or README updates for the other two stories.

What does this PR do?
Add an optional, experimental builtin plugin that sends configured questions and selected traffic content to a decision model through the System One HTTP API. It publishes typed evaluation results in a dedicated namespace. PPE policy uses those results to deny, restrict routing, request approval, or set headers. The embedding application applies the policy outcome.
The current proposal focus on the idea, how a design would work, how a configuration looks like and defining what would be the deliverables
